I'm not recommending this book, but I noticed some errors and wanted to post my findings in case anyone else got frustrated.

First of all, there is an available pgn of the positions only (both below links have the exact same pgn). In Ending 97 the pgn moved the black bishop from b2 to c2. The correct FEN is q5k1/8/P6K/2p5/3p2N1/8/1b3R2/8. Other than that, the pgn faithfully reflects the book's diagrams and captions.

Now to the book itself. Ending 162 - Ending 166 (pages 182-187) have the wrong diagrams. I found these five in van der Heiden (2000) Endgame Study Database. The mistake was simple, the five diagrams were just shifted around. So the diagram under Ending 162 belongs to 163, 163 to 164, 164 to 165, 165 to 166, and the diagram under Ending 166 belongs to 162.

I'm not sure how carefully I will look at Chernev's solutions, but if I find any more errors I will post them here.

The below is Ending 164 on page 184, but as just discussed the diagram is mismatched. I took the correct diagram from page 183. I put Chernev's solution in the pgn attachment, in case you want to try solving it. Chernev's solution mostly agrees with van der Heiden's, except that Chernev stops at move seven, while van der Heiden analyzes to move 13 with black's attempts to win.
